By 2026, micro-niche SaaS—highly specialized software serving underserved industries—will dominate due to AI automation, verticalization trends, and increasing demand for domain expertise. According to Gartner, 70% of enterprises will adopt niche SaaS solutions by 2026, up from 30% in 2023, driven by efficiency needs and AI integration.
